Abstract
A particle dispersion method for dispersing particles (500) fixed on the inner surface of a container (12) into a liquid. The particle dispersion method includes a discharge step of discharging a liquid into the container (12). The container (12) has a cylindrical main body part (310), and an inclined part (311) having an inner diameter that decreases from the main body part (310) side to the bottom part side and having a constant angle relative to the central axis of the container. In the discharge step, the liquid is discharged from above the inclined part (311) toward the inclined part (311) on the side opposite the particles (500) fixed to the inner surface of the container (12) across the central axis (300) of the container (12).
Claims20
A particle dispersion method for dispersing particles fixed on the inner surface of a container in a liquid, the method comprising:
- an installation step of installing a container having a cylindrical main body part and an inclined part whose inner diameter decreases from the main body part side to the bottom part side and whose angle with respect to the central axis of the container is constant;
- a discharge step of discharging the liquid from above an inclined part toward the inclined part on the side opposite the particles fixed to the inner surface of the container across the central axis of the container.
A particle dispersion device comprising:
- a setting part configured to be installed a container having a cylindrical main body part and an inclined part having a structure that becomes smaller from the main body part side to the bottom part side and having an angle relative to the central axis of the container is constant;
- a nozzle configured to discharge a liquid into the container;
- and
- a control unit configured to control the nozzle so as to discharge the liquid from above the inclined part toward the inclined part on the opposite side of the particles fixed to the inner surface of the container across the central axis of the container.
A nucleic acid analyzer comprising:
- a setting part configured to be installed a container having a cylindrical main body part and an inclined part having a structure that becomes smaller from the main body part side to the bottom part side and having an angle relative to the central axis of the container is constant;
- a nozzle configured to discharge a liquid into the container;
- a control unit configured to control the nozzle so as to discharge the liquid from above the inclined part toward the inclined part on the opposite side of the particles fixed to the inner surface of the container across the central axis of the container;
- an amplification part for amplifying nucleic acid in the liquid prepared by dispersing particles fixed on the inner surface of the container by the particle dispersion device;
- and
- a detection unit for detecting the amplified nucleic acid.
